NeoPixel is a very practical RGB LED that you can use with just one microcontroller pin, enabling you to use it multiple times by tying it all at once. On this circular card, 24 NeoPixels are connected to each other. You can also use multiple LED rings by connecting the cards in succession.
There are 24 pieces of 5mm x 5mm NeoPixel LED on the card. It has 24-bit color depth. It operates with 4-7V DC voltage (ideal operating voltage is 5V). A maximum of 20mA per pixel is required. Because they are driven at constant current, the brightness of your NeoPixel will not diminish even when the battery you use in your progeny is weak. Using Arduino, you can drive NeoPixel at up to 500 fps at 500 fps. Arduino's processing power and memory are not enough to drive more NeoPixels.
